HEAT EXCHANGER AND REFRIGERATION DEVICE WITH SAME

摘要

An economizer heat exchanger (12) is provided with an inner flow path (22) and outer flow paths (23) which are disposed around the inner flow path (22), and the economizer heat exchanger (12) exchanges heat between fluid which flows in the inner flow path (22) and fluid which flows in the outer flow paths (23). The fluid which flows in the inner flow path (22) is a refrigerant which flows in the inner flow path (22) in a two-phase state of gas and liquid, and the inner flow path (22) is provided with centrifugal force application mechanisms (24) which are configured in such a manner that a centrifugal force acts on the refrigerant which flows in the inner flow path (22).
